OkHttp
OkHttp is a popular tool that helps mobile app developers handle internet connections in Android apps. Think of it like a delivery service for apps - it manages how apps send and receive information over the internet. Developers choose OkHttp because it's reliable, fast, and makes it easier to do things like download files, connect to company servers, or fetch information from other online services. It's particularly known for working well even when internet connections are unstable. Similar tools include Retrofit (which often works together with OkHttp) and Volley. When you see OkHttp mentioned in a resume, it shows the candidate has experience with handling internet-related tasks in Android apps.
